    摘要: A hay bale lifting and transport device is mounted on a transport vehicle having a cab and having a rear bed area located behind the cab which defines a generally rectangular shaped, exposed top planar surface. The lifting apparatus includes a pair of elongate hay bale spikes affixed to a mounting assembly so that the spikes are spaced apart a fixed distance and are arranged in a plane parallel to one another. The spikes and mounting assembly are received in an opening formed in the rear planar bed of the transport vehicle when the spikes are in a first, fully retracted position, the central axis of each of the spikes being located below the plane of the rear bed. An actuating mechanism acts upon the mounting assembly for moving the pair of spikes around a pivot axis between the fully retracted position and an extended position in which the spikes are arranged to engage a bale of hay.

    摘要: A fluid compressor 10 comprising a stator 22, having a bore shaped first chamber 26 and an annular second chamber 30, and a piston 18 comprising a central piston rod 36 having a first piston head 44 and a concentrically arranged cylindrical piston sleeve 38 having a second piston head 48. The stator 22 and piston 18 together define a first compression chamber 12, a second compression chamber 14 provided concentrically around the first chamber 12, and a third compression chamber 16 provided concentrically around the first chamber 12 and linearly with the second chamber 14. The compression chambers 12, 14, 16 are interconnected via intercooling conduits 72, 74. A hydraulic actuator 20 is coupled to the piston 18 by a hydraulic ram 82. During left to right movement of the piston 18 fluid enters the third chamber 16 and fluid is compressed in the second chamber 14.
